Abstract
In this experimental, effects of phytaze enzyme and substitute fish meal with soy meal were studied in 8 weeks, on growth performance and carcass quality in beluga juvenile. The beluga juvenile (weight mean 80.65±2.16g) were distributed in 21 fibreglasses tank and feed with 7 diets that were contains different levels of soy and phytase. Experimental dietaries were prepared include control diet wherein was not use of soy meal and phytase enzyme and other 6 experimental dietaries in factorial method 2×3 include tow levels 70 and 40 percentage substitute fish meal with soy meal and three levels phytase (zero, 1000 and 2000 IU/kg). In the end growth tests, significant differences were found in growth performance (p
